You should ideally schedule a professional tune-up twice a year: once in the spring for your cooling system and once in the autumn for your heating equipment. Regular maintenance ensures your systems operate efficiently, minimizes the risk of unexpected breakdowns, and helps preserve your manufacturer’s warranty coverage.
